​Construction recently completed on ERA’s building reinforcement design for the addition of a 30’x40’ bi-fold hangar door at the Construction Engineering Research Laboratory (CERL) in partnership with the University of Illinois. The TESS building houses a three-dimensional “shake table” that tests the ability of systems, facilities, and equipment to survive under realistic conditions of shock, vibration, and earthquake ground motion. The much larger door opening allows engineers to assess the seismic vulnerabilities of a wide variety of configurations that were previously not possible due to access limitations.

​Two projects designed by ERA recently completed construction this spring at the Urbana-Champaign Sanitary District’s Northeast Plant located in Urbana, IL. A new aluminum stair system was designed to provide safe access for the UCSD maintenance staff to the adjacent Digester covers. Also, deteriorating roads within the plant were reconstructed with improved drainage ditches and successfully started and finished without interruption to plant deliveries.
